Quick Answer: Which Of The Following Is A Primary Storage Device?

Is modem a storage device?

A modem does not provide any significant storage that is useful to the user.

A flash drive does not provide any form of real time interface to other network systems..

What are the two types of primary storage?

There are two types of memory in primary memory, RAM and ROM.

What is difference between primary and secondary storage?

Primary storage refers to the main storage of the computer or main memory which is the random access memory or RAM. Secondary storage, on the other hand, refers to the external storage devices used to store data on a long-term basis.

What is the purpose of primary memory?

Primary memory is computer memory that a processor or computer accesses first or directly. It allows a processor to access running execution applications and services that are temporarily stored in a specific memory location. Primary memory is also known as primary storage or main memory.

What are the characteristics of primary memory?

Characteristics of Main MemoryThese are semiconductor memories.It is known as the main memory.Usually volatile memory.Data is lost in case power is switched off.It is the working memory of the computer.Faster than secondary memories.A computer cannot run without the primary memory.Apr 20, 2020

Is ROM is a secondary memory?

Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.

What is primary and secondary memory with example?

The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept.

What are primary and secondary storage devices?

Primary memory usually refers to Random Access Memory (RAM), while secondary storage refers to devices such as hard disk drives, solid state drives, removable “USB” drives, CDs, and DVDs. …

What is primary storage devices with examples?

RAM (random access memory) and cache are both examples of a primary storage device. The image shows three different types of storage for computer data. Primary storage’s key differences from other storage devices are that it is directly accessible by the CPU, is volatile, and is non-removable.

Which of the following is an example of a secondary storage device?

Examples of secondary storage devices include external hard drives, USB flash drives, and tape drives. These devices must be connected to a computer’s external I/O ports in order to be accessed by the system. They may or may not require their own power supply.

Which of the following is the smallest storage device?

A. The smallest unit of data in a computer is called Bit (Binary Digit). A bit has a single binary value, either 0 or 1. In most computer systems, there are eight bits in a byte. among the following: Megabyte is the smallest.

What are 2 types of data storage?

Types of Data StorageHard Drives.Solid-State Drives (SSD)CD/DVD Drives.Flash Drives.And More.Mar 18, 2019

How many types of secondary memory are there?

two typesDepending on whether secondary memory device is part of CPU or not, there are two types of secondary memory – fixed and removable.

Is ROM a primary storage device?

ROM: Unlike RAM, Read Only Memory (ROM) is both a non-volatile and permanent form of primary storage. ROM retains its contents even if the device loses power. … Primary storage provides fast access to CPU, which allows active programs to deliver optimal performance to the end-user.

Which of the following is a primary memory?

Primary memory is computer memory that is accessed directly by the CPU. This includes several types of memory, such as the processor cache and system ROM. However, in most cases, primary memory refers to system RAM.

What is difference between primary and secondary memory?

KEY DIFFERENCE Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor. … Primary memory is both volatile & nonvolatile whereas Secondary memory is always a non-volatile memory.

Why is primary memory called so?

Its called primary because your computer processor use it as the base to store anything that’s going in process ,thus whatever is being processed in the moment ,is stored there because its fast so as to match the speed of processor.

Which of the following is a storage device?

A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
